Multi-threaded programs really do need those cache flushes to implement their interprocessor communications, don't they? It seems to me that they would be the ones most likely to hit this problem.

It has yet to be established whether hammer techniques can result in a correct data+ECC pattern. If so, it should be possible to permute the memory in a way that defeats this, either on the memory module or the memory controller.
That would make a good research paper for someone.
Yes, you beat me to it. A correctly-configured ECC motherboard with real ECC memory would defeat this. Watch out for fake ECC memory that just simulates the correction bits.
Once memory starts being vulnerable to row interference, having a machine without ECC becomes much more dangerous, regardless of this exploit.
Yet another reason to push shared providers for ECC memory. The error correcting memory is so far not vulnerable to this attack, all the researchers that have tried it report that ECC memory identifies and corrects the corruptions. Of course some attackers may have found a way, but ECC minimizes the risk
Amazon says it uses ECC in their AWS machines, but other big hosts like Equinix say that ECC memory is "available". Be careful about your hosting, folks.
6 months Contract to Hire
That is what I see all the time as well, and I know they won't get filled.
Market rate is set by both the buyer and the seller. Or in this case, the employer and the employee.
How do I know they will struggle to get the good people?
Because of employers like mine!
We've got similar skill requirements and six month contracts that on the low end START at about $50/hr, with many going for $75/hr, $85/hr, or more. That's what we pay to get skilled people. Many apply, there are lots of people with documented successful histories, and we can choose among people with fantastic abilities.
While the employer may eventually find someone who will take the contract job for $30/hr, that is below market rate for talented people. Eventually someone will get desperate enough for it, or maybe they'll be gullible enough for it, and they'll take the job. It is not really a shortage of workers, just a market force at work.
Some workers will demand too much money for the skills they offer, some employers will offer too little money for the skills they demand. In both of those cases the market tends to work itself out, with either the workers eventually settling for lower paying jobs or the employer eventually settling for lower quality workers or higher rates.
You have the Part 15 and ISM services for that. You really can buy a microwave link that's metropolitan-distance and legal to use.
We lost much of our 440 capability to PAVE PAWS in California. Remember, Amateur Radio is not the primary service on many bands. The military is on 440.
If you want that nearly infinite microwave spectrum, you have the Part 15 and ISM services. Absolutely nothing is stopping you. Power is not the issue with those frequencies, it's line of sight and Fresnel zones.
No, I absolutely do not have to prefix my words with anything. You do that by posting as an anonymous coward. I use my real name to indicate that I stand behind my words.
Yes. The usual mechanism here would be WiFi security, with HTTPS or SSL inside of it.
OK, no real technical data and some absurd claims here.
First all-digital transceiver? No. There have been others. Especially if you allow them to have a DAC and an ADC and no other components in the analog domain, but even without that, there are lots of IoT-class radios with direct-to-digital detectors and digital outputs directly to the antenna. You might have one in your car remote (mine is two-way).
And they have to use patented algorithms? Everybody else can get along with well-known technology old enough that any applicable patents are long expired.
It would be nicer if there was some information about what they are actually doing. If they really have patented it, there's no reason to hold back.

It is actually kind of sad if you know their history.
Back in the day they were competing with Palm, and had Windows CE and Pocket PC 2000. When PocketPC 2002 came out my employer switched over from Palm and I got to rewrite a bunch of tools. They did pretty good for a while with Mobile 2003, and Windows Mobile 5. It knocked Palm down several notches in the mobile market, with Palm losing value and getting bought out in 2005.
The fun thing about that era is that there were phones with PDAs in them, you can go back to "Pocket PC Phone Edition" for that. Each version of Windows Mobile supported running in phones, but they never took off.
The iPod was getting some power and some apps, but I loved that with a single CF card I could have my entire music library on my device; the Axim x51v used the same audio chipset as the iPod of the era coupled with better playback software where you could mix and such. It also offered all kinds of apps making the device useful for the other common tasks of the time like calendar, email, and web over both wifi and bluetooth.
Again you could get phones running WM5 and WM6 with all their apps, and in late 2006 they had 51% of the market. Blackberry had 37%, Palm was 9%, and Symbian at 9%.
Then came the iPhone. At the time I didn't really see the reason for the hype, when it came to processor power, memory, and even 3D graphics the iPhone was less powerful than my Windows 6 phone.
As the numbers came back, iOS rose and WM feel by the same percent; the other companies were flat in market share. By early 2007 Windows Mobile drooped to 42% and iOS was at 11%. By 2008, WM had 29% and iOS 19% and Android had entered at 2%. By 2010 Windows Mobile devices had dropped to 7% market share, Blackberry had dropped to 25%, Palm to 3%, and Symbian at 2%.
Phones running Windows Mobile continued to exist, but that's about it. Three more versions of Windows Mobile, the three editions as Windows Phone, they have never been able to get their market share back anywhere near 2006 levels.
People will buy anything that's one to a customer.
